Black power under printer

Hi guys,

I'm dealing with a weird phenomenon with my Prusa MK2S.

I recently changed my heatbed, and since then I've been seeing black powder beneath my printer, see pictures:


Any idea what this is and whether I should worry?

Thanks,
Ram.

That is your y-axis belt slowly disentigrating. You should check the movement on your y axis and either loosen or tighten it. Looks lime loosen it a little.

Also the idler position should be adjusted. R/L

As already mentioned the belt is rubbing against something. Check the whole belt path. Motor - Bed holder - Idler. All of them need to be perfectly in line.
No worries about the used belt, It's still good and don't need to be replaced.
